Bug#446315: xserver-xorg-video-ati: crashes in R and Blender, and incomlete drawing of glut (opengl) wire objects

Hi Brice,

I finally managed to get the output from gdb (having installed libgl1-mesa-dri-dbg as suggested - sorry for such a long delay.

Many times the crash when running in gdb would freeze my system - sometimes restarting X would work, other times having to just use the power button).

This time i got lucky (i don't understand why the symptoms aren't exactly the same each time) and i copied the output to the attached file.



P.S. Should i log the incomplete drawing of glut shapes as a separate bug?

Blender crashes before even getting started (segmentation fault).

Can you  catch a backtrace in gdb? Assuming the problem is in
libgl1-mesa-dri as Michel said, you might want to install
libgl1-mesa-dri-dbg, and enter 'bt full' in gdb once the crash occurred.
